FM motor 230V & 460V Performance A Brushless Servo FM The FM motor is a high performance brushless A servo motor range matched for use with ontrol Techniques drives. FM is an acronym for Flexible, designed to accommodate a wide range of applications. The motors are available in six frame sizes with various mounting arrangements and motor lengths. Key Features and Options: Wide torque range 6.6 to 647 lb-in (0.75 to 73.2 Nm) 4096 ppr encoder standard Various Sizes and lengths: 055, 075, 095, 115, 142 and 190 mm Different shaft diameter options Various front flange mounting arrangements 90 degree connectors (rotatable) Brake options Sealing to IP65 Benefits: Unimotor FM allows various feedback devices to be used, as standard an incremental encoder is fitted as this offers an optimum balance of cost and performance. Sin/os feedback can be selected for increased resolution and absolute feedback. Resolver feedback is available for increased reliability in extreme environments. New low cost inductive option.

Flexibility of the FM range always ensure the best fit for your application, as well as the various physical sizes and feedback devices available, options extend to the type of connectors fitted. This configuration is designed with low cogging torque to provide smooth operation and excellent velocity regulation. Unimotor FM is suitable for applications where precision motion and/or dynamic control is required. Typical applications include: High speed machinery Flying shear and rotary knife applications Pick and place Materials handling Printing Textile machinery

NT 230V The NT is an economical, high performance motor manufactured to maximize torque and minimize size. The NT motor uses powerful Neodymium magnets and is manufactured with a segmented core to maximize stator efficiency and further reduce size. Very low inertia for applications that demand high accel and cycle rates English (NEMA 23 or 34) or Metric (IE- 72-1) flanges With or without holding brakes The standard encoder resolution is 2048 lines per rev. NT motors can be ordered with MS style connectors, 1 meter Flying Leads or 1 meter Flying Leads with MS connectors, direct connect All models are rated IP65 Medium inertia options NT motors are now available with direct motor to drive connector terminations for Epsilon EP, Unidrive SP & Digitax ST.
